Air-supported structures



FIG. 1 is a side elevation view of an air-supported structure combination showing my design,

FIG. 2 is a plan view of the air-supported structures in FIG. 1,

FIG. 3 is a front elevation view of the air-supported structures in FIG. 1,

FIG. 4 is a rear elevation view of the main air-supported structure in FIG. 1,

FIGS. 5-11 inclusive, are transverse sectional views _ of the air-supported structure illustrating the sectional profile configuration of the air-supported structure at corresponding section lines in FIGS. 1 and 2.

The air-structures are illustrated in an inflated condition. Each is made of a suitable flexible plastic sheet or membrane. The elongated main structure is symmetrical about a vertical plane of symmetry passing through its longitudinal axis and has the same configuration on opposite sides of the vertical plane of symmetry so that an elevation view of one side illustrates the opposite side in FIG. 1. The smaller structure is bubble-shaped and is joined to the main structure by an enclosed passageway. 

The ornamental design for air-supported structures, as shown and described.
